Muffler help

[Georgelogue]

The baffles and end cap came out of my muffler on a ride the other day. I was told that my exhaust is a mac exhaust. I can't see any marks/serial numbers on it to determine the make of it. I contacted mac several times and i think they may be shut down. (no one answers the phone or emails) I am looking for either a whole new muffler or a new baffle/end cap combo. The inside diameter of my current muffler is 3 5/8. I am having trouble locating baffles and end cap for that size. Does anyone have any recommendations? Any recommendations for a whole new muffler? this is for my 79 CB750L.

Thanks

I don’t know about a new muffler but complete MAC exhausts are available new for your bike in a load of bike parts stores and on eBay

Is it one like this?

If so I have a new muffler that I can sell you. It's too big for a CB550 or 500, but I think it was from a CB750 system.
